Review comments on the first edition: ...an excellent textbook which is well planned, well written, and pitched at the correct level for psychology students...I would not hesitate to recommend Greene and d'Oliveira to all psychology students looking for an introductory text on statistical methodology. - Bulletin of the British Psychological Society. This book shows psychology students: how psychologists plan experiments and statistical tests; why they must plan them within certain constraints; and how they can analyse and make sense of their results. The approach is that: theory is always presented together with practical examples; theoretical points are summarized and understanding of them tested; and statistical principles are introduced as part and parcel of the principles of experimental design. The second edition of this widely acclaimed text is an accessible and comprehensible introduction to the use of statistical tests in psychology experiments: statistics without panic. Presented in a new textbook format, its key objective is to enable students to select appropriate statistical tests to evaluate the significance of data obtained from psychological experiments. Improvements in the organization of chapters emphasize even more clearly the principle of introducing complex experimental designs on a 'need to know' basis, leaving more space for an extended interpretation of analysis of variance. In an important development for the second edition, students are introduced to modern statistical packages as a useful tool for calculations, the emphasis being on understanding and interpretation.
